Heucherella plant named ‘Sunrise Falls’

ABSTRACT

A new and distinct  Heucherella  plant substantially as shown and described, characterized by a vigorous, trailing habit, large, deeply lobed leaves, leaves yellow to lime green in spring and summer with red tones in fall and winter, a dark splatter pattern on the veins, and excellent vigor.

Botanical denomination: Heucherella hybrid.

Variety designation: ‘Sunrise Falls’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Heucherella and given the cultivar name of ‘Sunrise Falls’. Heucherella is in the family Saxifragaceae. Heucherella ‘Sunrise Falls’ originated from a controlled cross between a proprietary unreleased seedlings Heuchera 217-4, as the seed parent, and Tiarella 42-5, as the pollen parent.

Compared to the seed parent Heuchera 217-4, the new cultivar is trailing rather than clumping.

Compared to Tiarella 42-5, the new cultivar has yellow to lime leaves rather than green.

Compared to Heucherella ‘Yellowstone Falls’, U.S. Plant Pat. No. 22,313, the new cultivar is larger, with leaves that are larger and more deeply lobed, and the leaves get red tones in the fall rather than staying yellow green.

SUMMARY OF THE INVENTION

This new Heucherella is unique in having the following characteristics:

-   -   1. a vigorous, trailing habit,     -   2. large, deeply lobed leaves,     -   3. leaves yellow to lime green in spring and summer with red         tones in fall and winter     -   4. a dark splatter pattern on the veins, and     -   5. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
